Patton electronic 29XX manual Loopback Config dsx1LoopbackConfig, Send Code dsx1SendCode

Access Server Administrators’ Reference Guide 22 • T1/E1 Link

•linkYellowOn—Force the transmission of a yellow alarm even if the received signal is in frame.

•linkYellowDisable—Do NOT transmit a yellow alarm even if the received signal is out of frame.

Loopback Config (dsx1LoopbackConfig)

This variable represents the loopback configuration of the DS1 interface. Agents supporting read/write access should return badValue in response to a requested loopback state that the interface does not support. The val- ues mean:

•dsx1NoLoop—Not in the loopback state. A device that is not capable of performing a loopback on the interface shall always return this as it's value.

•dsx1PayloadLoop—The received signal at this interface is looped through the device. Typically the received signal is looped back for retransmission after it has passed through the device's framing function.

•dsx1LineLoop—The received signal at this interface does not go through the device (minimum penetra- tion) but is looped back out.

•dsx1OtherLoop—Loopbacks that are not defined here.

Send Code (dsx1SendCode)

This variable indicates what type of code is being sent across the DS1 interface by the device. The values mean:

•dsx1SendNoCode—Sending looped or normal data

•dsx1SendLineCode—Sending a request for a line loopback

•dsx1SendPayloadCode—Sending a request for a payload loopback

•dsx1SendResetCode—Sending a loopback termination request

•dsx1SendQRS—Sending a Quasi-Random Signal (QRS) test pattern

•dsx1Send511Pattern—Sending a 511 bit fixed test pattern

•dsx1Send3in24Pattern—Sending a fixed test pattern of 3 bits set in 24

•dsx1SendOtherTestPattern—Sending a test pattern other than those described by this object.

Error Injection (linkInjectError)

Force an output error to see if the other end detects it

•noErrorInjection(0)

•injectCRCerrorBurst(1)

•injectLineErrorBurst(2)
